[HTCondor-users] POOL_HISTORY_MAX_STORAGE seems to be ignored on Windows

[Alexey Smirnov <smirnalex@xxxxxxxxx>]

Hi!

We are running condor 8.8.0 on Windows cluster and noticed that the history files directory grows indefinitely regardless the settings "POOL_HISTORY_MAX_STORAGE = 50000000":

ÂDirectory of C:\condor\history

[...]

CollectorLog confirms that all settings are correct:
12/18/19 11:44:17 Configuration: SAMPLING_INTERVAL=60, MAX_STORAGE=50000000, MaxFileSize=1666666, POOL_HISTORY_DIR=C:\condor\history

If I manually delete ".old" files then almost immediately those big files are renamed into ".old". Therefore my guess is that the problem is related to some bug in condor when it rotates history files reached the size limit. Most probably "rename" function is used without prior deleting of old file. This is crucial in Windows compare to Linux since rename simply fails if destination file already exists.

Any ideas if anything else could be a reason?

Thank you!
